Diisopropylethylamine → N-(6-Chloro-4-o-tolyl-pyridin-3-yl)-N-methyl-3,5-bis-trifluoromethyl-benzamide

Participants

Reaction Steps

3,5-Bis-trifluoromethylbenzoyl chloride (76 mg, 0.28 mmol, CAS RN 1271-19-8) was added to a solution of 6-chloro-N-methyl-4-o-tolylpyridin-3-amine (30 mg, 0.13 mmol, prepared as described in WO2005/002577) and DIPEA (50 μL, 0.29 mmol) in THF (1.5 mL). The reaction mixture was stirred overnight, filtered and all volatiles removed in vacuo. The desired product was isolated by flash chromatography on silica gel (25% EtOAc in n-hexane) as a waxy solid (48 mg, 79%). MS (ESI): m/z=472.9 [M+H]+.
